Reduced heart rate variability has been found in infants who later succumb to the sudden infant death syndrome (SIDS). To determine whether respiratory sinus arrhythmia, a major component of heart rate variability, is also reduced in SIDS victims, nighttime portions of eighteen 24-h recordings of ECG and respiration from infants who later died of SIDS and(More)
We examined the potential to classify sleep and waking state over the first 6 months of life in normal infants using only cardiac and respiratory measures. Twelve hour all-night polygraph recordings which included EEG, eye movement, whole body movement, facial muscle electromyographic, cardiac, and respiratory activity from 25 normal infants were collected(More)
Victims of the sudden infant death syndrome (SIDS) have higher overall heart rates prior to death than do control infants (1). The objective of this study was to partition these heart rate differences by state and to identify any state-dependent differences in heart rate variability and respiratory rate and variability. Twenty-two recordings of(More)
Development of heart rate variation in three frequency ranges was examined during sleep-walking states in normal infants over the first 6 mo of life. Extent of all three types of heart rate variation decreased from 1 wk to 1 mo of age. Extent of respiratory sinus arrhythmia increased from 1 mo to 6 mo during all sleep-waking states, with the increase most(More)
Infants who later succumb to the sudden infant death syndrome (SIDS) exhibit lower overall heart rate variability during waking than do other infants. This study attempts to determine which type or types of heart rate variation are reduced in SIDS victims. Long-term recordings of heart rate and respiration were obtained from normal infants and infants who(More)
Coordination between physiological measures (i.e., the tendency for measures to co-vary with each other) develops with maturation in the infant. We hypothesized that correlations between cardiorespiratory measures would increase with maturation in normal infants and that infants destined to die of sudden infant death syndrome (SIDS) would show lower(More)
